The singer has stayed mostly mum since the announcement, while her husband, set to host the Kids’ Choice Awards on Saturday, let slip how his wife reacted to the positive pregnancy test.

“I know that my husband told everybody what I said, my quote when we found out, ‘This [blank] just got real,” she said. “It’s true when that moment occurs to you that, yeah, there’s going to be a human being growing inside of you. It’s reality. It’s amazing.”

“We’re thrilled and so excited,” said Fergie, who’s been married to Duhamel since 2009.

While the singer has slowed the pace of her music career to focus on becoming a mom, she confirmed to GMA that she is still writing music wherever, and whenever, she finds the inspiration.

“It always is so spastic, my writing,” she said. “I could have one thought and it be so weird and have nothing to do with anything that’s going on in my life.”

She is also taking on a new adventure, teaming up with the makeup company Wet ‘n’ Wild, for which she serves as its global beauty ambassador, to develop the Perfect Pout V.I. Pink lip color.

A portion of the proceeds from each lipstick sold will be donated by the company to the American Foundation for AIDS Research (amfAR).

“We’re so excited because it’s a cause that’s near and dear to me,” Fergie said.
